| JP1/2 through 9 are the BIOS address select. The factory |
| setting is C800 and is set with trace wires at JP1/jumpers |
| 2, 3, 5, 6, and 9. BIOS address may be changed by cutting |
| the traces and closing other pins, using the information |
| in the table above. However, any modifications to the |
| controller will void the warranty. |
